LOST LAKE NATURE PARK: Goose Drama, a Star-studded Insect and More

Ring-necked Ducks – 3 males and a female – in Lost Lake

Most of the action at Lost Lake Nature Park in the last few weeks has centered around which pair of Canada Geese control which section of the lake. These normally mild-mannered birds can act like a flock of drama queens when establishing territory and nesting. When I arrived for the first time two weeks ago, the weather was still cold, but some geese tempers were simmering!

I’d just read The Geese of Beaver Bog by Bernd Heinrich and supplemented my limited Canada Goose knowledge with Donald Stokes’ Guide to Bird Behavior, Volume 1 – so I was curious to see if I could read Canada Goose body language for the first time. Well, it was quite an exciting set of lessons from the geese themselves!

Then I went on to explore the more mellow residents of Lost Lake Nature Park and also fell in love with some wildflowers and a momentarily glamorous insect.

 Drama at the Lake!

When I stepped out of my car during my first visit, a male Canada Goose (Branta canadensis) and his mate saw me and moved away from the floating dock. The female swam calmly to the west end of the lake while the male patrolled the center.

He turned his head toward me as I reached the dock and kept me in sight all the time. It was a cold day with a strong north wind, unusual for late April. As I walked along the shore toward the east, I heard the male goose honking wildly and turned to see him making a bee-line straight toward me across the pond! When he reached the dock, he took to the air and flew at me, honking wildly, his wings snapping just above my head. Needless to say, I did not raise my camera for a photo! He dropped heavily into the water behind me and gave what the Stokes guide called “the head flip,” stretching his neck high, shaking his head from side to side and giving what Stokes calls “quiet grunts” indicating that the goose is apprehensive or disturbed.

I was puzzled as to what I’d done to receive what was so clearly a threat. So after a few minutes, I moved back to the dock and finally noticed what should have been obvious before. A goose nest rested among the stalks on the island in the lake, lined with feathers from the female’s chest (a “brood patch”) and perhaps some cat-tail fluff. Silly me, I didn’t realize that the whole south side of the pond was this pair’s territory and they had started a family there!

A quite obvious goose nest probably lined with some of the female’s breast feathers and perhaps some cat-tail fluff.

On the far side of the pond, a second pair of geese were already nesting. Periodically the first male would venture somewhat toward the second pair and the male of that pair would stand with his neck very straight and his body tilted slightly forward. If I understand the Stokes Guide correctly, he was making an “I’m aware of you” signal to the other male, indicating that he sensed a possible confrontation. The first male circled away each time.

The male of a second pair raised his neck and head to indicate to the other male that he was approaching too close to his nest.

Later in that visit, the female goose of the first pair rejoined her mate near the nest. As she approached, they both began what Stokes calls a “greeting ceremony.” She would call softly “hink, hink” as she swam and he would respond almost simultaneously with his loud “A-honk!” When she reached him, she put her bill near his, almost tucking her head beneath his lower bill.

The female joined the male and they did a bit of the greeting ceremony, accompanied by soft calls.
The female placed her head right below the male’s during their greeting.

Then to my amusement, they both turned in my direction and seemed to be scolding me loudly for having dared to get that close to their beautiful nest! Look at the male’s eye turned right toward me and the female facing me directly! It was just a reminder….

The two geese honk loudly while facing me, perhaps as warning to not get so close to their nest next time!

On my next visit to the dock, it was the female who gave me the warning – a stern look as she sat on her nest. That neck position with a straight, lowered head aimed right at me is a threat pose. She remembered this possible trespasser with the camera!

The female goose takes a threat pose from her nest on my second visit. She knows a trespasser when she sees one!

On my third visit, she still kept an eye on me, but seemed more relaxed at my presence, just turning her head to let me know that I was seen. That extended wing may be creating a warm blanket for her eggs, if any,  as well as for her.

The nesting female was more relaxed on my third visit.

A week later, I saw what I thought might be my first pair quietly feeding near the nest. Female geese leave the nest for up to an hour during incubation and these two were very close to the nest. It was a lovely warm day and the eggs, if there were any, were probably quite warm under the loose feathers and cat-tail down. I also spotted a third nest at the west end of the lake with one goose standing over it and the female of the second pair on the north side was still sitting on her nest.

But the Canada Goose treat of the day was that, on my way home,  I stopped to see two adult geese down the road at a residential pond, standing guard over seven little goslings calmly munching on the fresh green grass.

Other Wildlife Around the Lake Seemed More Relaxed

On that third visit, I also got treated to a pair of very calm Hooded Mergansers (Lophodytes cucullatus) floating around the bend in the island not far from the female goose. I’ve always seen photos of male Hooded Mergansers with their hoods raised dramatically, as in this photo by inaturalist.org photographer, Liam O’Brien.

The male at Lost Lake, however, seemed calm and collected. Through the veil of dry stalks, I was able to catch a quick shot of him. His relaxed crest lay in a slight droop at the back of his neck. The patterns of color on his body and head are so lovely and his bright, golden eye shone like a small gem in his velvety black head!

A male Hooded Merganser cruised Lost Lake in a relaxed mode, his dramatic crest a droop of feathers on the back of his neck.

On the coldest days, the Ring-necked Ducks (Aythya collaris) on the far edge of the lake tucked their bills into their back feathers. I thought perhaps they were keeping a low profile against the icy north wind that drove quick, short waves across the pond. In this relaxed posture, they simply drifted with the wind.

A Ring-necked Duck tucked his bill into his wing feathers, perhaps trying to cope with the icy wind.

A gathering of Painted Turtles (Chrysemys picta marginata) sun-bathed on the log where I’d first seen the Mergansers. This large one looked particularly content, despite its perpetual grimace.

Nearby, I think I kept hearing the snoring call of the Northern Leopard Frog (Rana pipiens). It’s as low as the Wood Frog’s, but less continuous and truly, very much like a snore! My recording was much too distant because the Leopard Frogs quieted every time I approached! But you can listen to one at this Macaulay Library link .

I didn’t know until this year that Leopard Frogs come out of hibernation from muddy lake bottoms in very early spring. I usually see them later in the spring or summer when they move into grassy areas. Here’s a picture of one a few summers back in just such an area at Bear Creek Nature Park. Snazzy spots, eh? 

Birds and Blossoms in the Wooded Areas

Lost Lake is surrounded by the high, dry hills cloaked by an Oak-Pine Barren. Birds flit in and out of the trees that surround the lake and the woods beyond. The rhythmic,  insistent call of the Northern Flicker (Colaptes auratus) sounded from the very top of a snag near the lake one sunny afternoon.

Male Northern Flicker high up on a snag over Lost Lake

In the photo that accompanies my recording below, you can see why he was once called the Yellow-shafted Flicker.

Nearby, in the grassy area just west of the caretakers’ house, a female Flicker was paying close attention! Male flickers have a black “mustache” on either side of their bill; females don’t.

A female Flicker seems to be listening to the male’s insistent call

Flickers are actually woodpeckers, though they spend a lot of time on the ground probing for their favorite food, ants. In fact, woodpeckers of several kinds busied themselves foraging on snags all over Lost Lake.That’s one of the reasons bird lovers leave dead trees standing in their woods when they can. They provide places to eat and nest for woodpeckers. Here a female Downy Woodpecker (Picoides pubescens) drills with great concentration on a dead limb, probably searching for beetle larvae.

The little Downy Woodpecker female is intent on finding some food in a dead limb.

A Red-bellied Woodpecker (Melanerpes carolinus) hitched quickly from branch to branch, probably looking for a similar meal, though he may also have been establishing a territory since he periodically let forth with his kwirrrr call.

In the White Pines (Pinus strobus) near the caretakers’ house, the cheery, tweeting call of the American Goldfinch (Spinus tristis) can be heard almost any day! I imagine they frequent the family’s thistle feeder all day long!

An American Goldfinch sits in the White Pines near the caretakers’ house enjoying their thistle feeder.

Occasionally, I’d see an Eastern Phoebe (Sayornis phoebe) in the area, sometimes on a low limb or sitting on the upturned boat near the shore.  It’s always darting down near the water’s edge, probably seeking out insects, since it’s a flycatcher.

A Phoebe resting on the upturned boat before darting down to feed at the shore.

On my last warm day visit, an Eastern Kingbird (Tyrannus tyrannus) had flown in on a south wind the night before. It took off  from a branch as I stepped out of my car, but then landed near the water, just as the Phoebe had. Perhaps you can just see the spot of greenery in its beak in the righthand photo? Nesting material, methinks! (Click on photos to enlarge; hover cursor for captions.)

Resilient Spring Flowers Flourish After a Prescribed Burn

A prescribed burn on April 27 nourished and warmed the native plants in Lost Lake’s natural areas.

The native plants of Lost Lake are a hardy bunch when it comes to fire! Shortly before a Lost Lake prescribed burn took place on April 27, I spotted two clusters of a classic spring flower, the native Round-lobed Hepatica (Hepatica americana). Some were along the trail to the Oak-Pine Barrens and the ones below were just at the edge of the grassy area west of the caretakers’ house.

A classic of early spring, Round-lobed Hepatica bloomed at the edge of the grassy area west of the caretakers’ house.

The fire crew was alerted to the presence of these little beauties and did their best to avoid them, leaving the ones in the photo above completely untouched, and singeing the ones along the trail, but leaving some leaves and blossoms. The surprise was that when I came back a week after the fire, the hepatica which was untouched by fire had disappeared  – perhaps finished off by warming temperatures or by a grazing deer. But the singed ones along the trail had made a comeback! These fire-adapted plants were producing new leaves and blossoms already on the blackened forest floor! The nutrients from the last year’s dry stalks had been released back into the soil by the fire and the blackened soil was nicely warmed again – so up they came for a second chance in the sun!

Likewise, down near the burned shore of the lake, under the trees, a huge patch of another native plant, May Apples (Podophyllum peltatum) emerged from the darkened soil. Their umbrella-like leaves were just beginning to open in the dappled light.

The native May-apples, also fire-adapted, emerged from the blackened soil to bloom in shade near the pond.

And of course the fire couldn’t reach the leaves of the Fragrant Water Lilies (Nymphaea odorata) rising from beneath the water near the edge of the lake. I never knew just how the lily pad took shape. Evidently they come up vertically like a wide blade of green and then eventually lay back on the water surface, as the various stages in the photo below suggest. I’m looking forward to the summer blossoms that bloom in the morning.

Fragrant Water Lily leaves rise from beneath the water and eventually lay back to become the lily pad.

And One Very Cool Insect with Stars at Its Feet

A tiny Water-Strider (fam. Gerridae) rowed across the surface of a wetland at the foot of the slope in the Oak-Pine Barrens. This little creature literally walks on water! In the shadows, it was easier to see its body and legs covered in thousands of tiny hairs which keep its body dry and light enough to perch above the water as it forages. Its long, flexible, strong legs distribute its body weight evenly so it can move easily across the surface of the water – hence its irreverent other name, the Jesus bug!  It steers using those long back legs and pierces its prey with the claws on the middle of its front leg!

But suddenly, when this amazing little creature moved into the sunlight, a small reflection of the sun shone like a star where each leg met the waterline.  I was delighted and immediately decided that the Water Strider could be the “star-studded finale” on the blog this week!

Seeing this tiny rower motor about the surface of a wetland, listening to the snap of a goose’s wings right over my head, or coming upon little lavender flower faces peering  up at me from the grass – those moments are epiphanies for me. They illuminate the reality that despite the presence of nature’s most invasive species, i.e. we humans! –   nature endlessly tries to adapt and survive, even if it means walking on the water, challenging a trespasser or springing out of burned earth. Surely such skills, daring, resilience and sheer beauty deserve our loyalty, protection and thoughtful stewardship.

Cranberry Lake Park: Have Hope! Sure but Subtle Signs of Spring!

The solstice has passed; the days and nights get equal time. But when I’m shivering, my fingers and ears go numb in a stiff  wind, I struggle to hold on to the idea that we’re heading into spring. Until, that is, I head into the parks.

Blog by Cam Mannino

In mid-March,  water birds began splashing down in Cranberry Lake, finding any narrow stretch of open water within the ice sheet. They floated and fed – until one glorious morning, the whole lake turned liquid and bright blue! Migrating flocks honked, chattered and wheeled overhead. Some stopped to rest and feed before heading further north; others explored nesting sites. Our year ’round residents tuned up their spring songs. Territories must be established! Potential mates must be impressed! Best of all, the tiny frogs thawed after their frozen winter state – and now they are  singing! Can genuine spring, with its fulsome birdsong and burgeoning buds be far behind? I think not!

Water Birds Arrive Early, Despite the Ice – and the Muskrats Emerge, too!

It always impresses me that some of the first migrators to arrive in early spring are the water birds! They float, seemingly content, in the icy cracks that form as the sun begins to work on the frozen lake surface. Their cold water strategies involve body fat, oiled feathers, down insulation, and a circulation system which allows cool blood coming up from their feet to pass close to  warm blood traveling down, warming it as it returns to the heart. Below a group of Common Mergansers – black-headed males and brown-headed females –  glided along a thin channel of water on the far side of Cranberry Lake’s iced-over surface.

Common Mergansers – black-headed males, brown-headed females – find a small slit of open water at Cranberry Lake early in March.

Off in the distance, the Wednesday birders spotted the hunched silhouette of a Muskrat (Ondatra zibethicus) perched on the edge of the ice as a goose floated nearby. It slipped in and out of the water, hungry no doubt for food but also for a meager scrap of sunlight after living under the ice all winter!

Two sunny but cold days later, the ice had disappeared and the lake was bright blue and busy with migrating ducks and geese. Two Bufflehead (Bucephala albeola) and a group of Ring-necked Ducks (Aythya collaris)black-and-white males and brown females –   dove and surfaced as they foraged near a Canada Goose (Branta canadensis).

A group of Ring-necked Ducks and two Bufflehead dove and rose next to a Canada Goose as they rested and foraged in the lake.

I got a bit closer to a Bufflehead by checking from the opposite side of the lake. This lone male rocked along on the surface, bobbing under to feed every few minutes. Cornell Lab of Ornithology says Bufflehead accomplish this dive  by compressing their feathers to drive out the air and then pitching forward. A few seconds later, they pop to the surface like a cork and float on.

The Bufflehead dives underwater by pitching forward with its feathers compressed to squeeze out the air, making it less buoyant and able to submerge.

And that same cold morning, what I think was a large muskrat came steaming across the pond toward the eastern side. At the time, I thought this bustling swimmer was a Beaver (Castor canadensis), since there is a large beaver lodge on the western side of the lake. But I’m just not sure of that, so I’m sticking with it being a large muskrat. In the water, its tail looked wide enough to be a beaver, but as it approached the shore, it just didn’t seem to be big enough to be a beaver, unless it was a yearling. And beavers tend to swim with only their heads out of the water. In any case, nice to see this furry fellow plying the pond in the sunshine. What do you think? Big muskrat or young beaver?

The width of this swimmer’s tail made me think this was a beaver, but I think now it was a large muskrat.
From this nearing shore photo, it appears I’ve seen a large muskrat, rather than a small beaver.

Hearing the ancient bugle of the Sandhill Crane (Antigone canadensis), I quickly looked up to see two in the distance, flying into the far end of the lake.  Aren’t we lucky that they breed in our wetlands?

 Spring Songs Signal the Beginning of the Mating Season

As I approached the park one icy afternoon, bright spring music reached my ear – Western Chorus Frogs. These tiny frogs (Pseudacris triseriata – about 1.5 inches long!) are daytime relatives of the nocturnal Spring Peepers (Pseudacris crucifer). They spent the winter frozen solid, no heartbeat, no brain activity, but protected by an anti-freeze of sorts that keeps their tissues from breaking down. Pretty amazing! They thaw out and start singing as the days lengthen. The first afternoon I scanned a wetland trying to see these tiny creatures that seemed to be singing right at my feet, but I could not spot one! So on a second try a few days later, I found a log to sit on near the wetland in the trees just east of the parking lot. After about 20 minutes with my binoculars, I finally spotted two (of the hundreds that were probably there!), the sacks beneath their chins bulging, as they tried to impress a female with their piercing calls. Have a look and a listen!

Two tiny Chorus Frogs with bulging necks sing to attract a mate in the shallow water of a wetland.

A male Northern Cardinal (Cardinalis cardinalis) sang from the tree tops in the eastern meadow, turning every few minutes to send his territory call in a new direction. He’s a bit faint on the recording below, so you might need to turn your volume up! I got a bit closer to another male in a bush near the parking lot later on. He was doing “call and response” with another cardinal hidden in the trees nearby.

And of course, the American Robins (Turdus migratorius) that went south to Ohio and Kentucky returned as well, joining the hardy ones that spent the winter here.

One of many Robins that have returned from Ohio and Kentucky to breed here in the summer.

His spring call is also a bit soft.  And he makes a longish pause before his second “tit whoo” call.

Woodpeckers, of course, use drumming to establish territories, rather than singing.  Both male and female Downy Woodpeckers (Picoides pubescens) attract mates and protect territories with drumming. You can hear their typical drum roll in this Cornell Lab recording which was put to use by the little female Downy below.

I get a huge kick out of hearing flocks of American Goldfinches (Spinus tristis) chirp in the shrubs and small trees. To my ear, they are the only bird that actually says “tweet, tweet, tweet!”  Have a listen at this link and see if you agree! The males are currently molting into their bright yellow summer outfits.

Groups of American Goldfinches are singing their “tweet, tweet” calls in Cranberry Lake Park right now.

On a bird walk one Wednesday, we heard the far distant, insistent drumming of a Pileated Woodpecker (Dryocopus pileatus). Mark, one of the great spotters in the bird group, finally located it with binoculars on a very distant tree, and suddenly its mate (we assumed) dove across the trail far ahead of us before slipping up and away between the trees. No chance for a photo.  But here’s an incredible closeup by talented photographer Monica Krancevic at iNaturalist.org.

The First Blooms and Some Sturdy Ferns Wait Patiently

The lovely red blossoms of the Silver Maple (Acer saccharinum) brighten gray days in early spring. They emerge on bare branches before the leaves and are pollinated by the wind before butterflies or other insects emerge and start to pollinate. Those big clusters of scarlet florets are a great food source for hungry squirrels in the spring, when food is scarce, since nuts and seeds are either already eaten or beginning to crack open and sprout.  Last week, I found these male (staminate) clusters fallen from the treetops onto the exposed roots of a large silver maple. I love how the red at the edge of the root echoes the red of the flowers.

The scarlet blossoms of a silver maple are echoed in the root of the tree itself.

Take a closer look at this cluster of florets, some still closed, others waving stamens that have already shed their pollen to wind.  Once pollinated, the female florets will produce winged fruits, called samaras.

A closeup of a cluster of male florets, some closed, some with their stamens already emptied of pollen.

Nearby on the trail to the lake, some sturdy ferns survived the winter with fertile fronds intact.  The brown beads below are the sporangia on the fertile fronds of the Sensitive Fern (Onoclea sensibilis) that carry the spores for this year’s crop of new plants. On the right, are the vegetative fronds that provide sugars through photosynthesis in the summer months.

And the feathery ones below left are the fertile fronds of Ostrich Fern (Matteuccia struthiopteris) whose spores will be released and carried by the wind in the spring. Their vegetative fronds on the right stood tall and bright green, taking advantage of the moist soil and spotty sunshine in the forest.

Spring Just Peeks Out…Here and There

A pair of Canada Geese rest in the quiet refuge of a shaded wetland

Behind a scrim of small trees on the way to the lake, I spotted these two Canada Geese floating serenely in a secluded wetland, away from the noisy flocks gathering on the lake. They reminded me that, at this time of year, spring has to be sought out. It appears and disappears. One day the lake is iced over, a few days later it’s rippling and blue and then the snow falls again. On some days, spring isn’t easily seen – just a few red blossom clusters floating in a vernal pool  or scattered on the lifeless grass. Sometimes spring can only be heard and not seen. Frogs as tiny as your thumb sing unseen one day and the next, perch on a bit of floating grass, their throats bulging with amorous sound. Flocks twitter or honk high in a cold blue sky or male birds rehearse the first tentative versions of their mating songs. Woodpeckers tap out a seductive rhythm on the bark of trees.

The Eastern Meadow at Cranberry Lake doesn’t look very spring-like yet – but the clues are there.

Early spring isn’t flamboyant and colorful, like it will be in a few weeks. It’s hesitant, waiting to be found and enjoyed if we can only slow down enough. If we watch, we’ll see it peeking through the alternating rain or snowfall, cracking and opening in thawing ponds or hear it whistling, chirping, trilling from inside the brush or high in the treetops. So I hope you have time to delight in these  subtle hints of early spring as they unfold. It won’t be long now…

Photos of the Week: Feisty Little Survivors Ride in on North Winds

Keep an eye on your thistle feeder!  Those little birds feeding greedily may not be the American Goldfinches (Spinus tristis) that we thought they were.  Just as in 2015, the Pine Siskins (Spinus pinus) rode the icy north winds down from Canada into Oakland Township. Some years they come; some years they don’t. Cornell Lab of Ornithology refers to them as erratic migrators who range like nomads across the continent each winter, foraging for seeds. Your finch feeder and mine are just the ticket to attract these wandering birds.

It’s easy to confuse Pine Siskins with other finches – particularly the female House Finch (Haemorhous mexicanus), which is also streaked with brown. But the smaller Pine Siskins have fine, sharp bills rather than the heavier bills of other finches, and their wings flash yellow as they scrabble with other birds at your feeder. While American Goldfinches sport some yellow feathers even in winter, they have clear breasts, not striped ones. Ben reminded me that the gregarious Pine Siskins also have a distinctive wheezy, high twitter and a distinctive “Zhreee” call that accompanies their feeding and flight. Check out the differences between these bird species below. (Click on photos to enlarge; hover cursor for captions.)

Pine Siskins have developed some pretty powerful winter survival strategies. Cornell Lab of Ornithology says that they get through frigid nights by “ramping up their metabolic rate,” which is already 40% higher than other songbirds their size. “When temperatures plunge as low as -70°C (–94°F),  they can accelerate that rate up to five times normal for several hours.” Plus they’re big eaters! They gain 50% more winter fat than other finches and can stuff their crops with “seeds totaling as much as 10% of their body mass…. The energy in that amount of food could get them through 5–6 nighttime hours of subzero temperatures.”

I try not to worry too much if the Pine Siskins monopolize our feeder for a while. So far, the American Goldfinches seem to find their moments to feed. And Pine Siskins pester their own kind as readily as they do their finch relatives, as you’ll see in the slideshow below! (Click on the pause button if you need more time for captions.)

So enjoy these feisty little travelers while you can.  You never know where they’ll spend next winter!

Cranberry Lake Park: Prepping for Winter, Sowing for Spring

One of the many spots where meadow meets woods at Cranberry Lake Park

Cranberry Lake Park, with its varied habitats, gives an autumn visitor lots of possibilities. In October, the lake hosts huge bobbing rafts of water birds, feeding and resting on their way south. The grassy trails lead you to expansive meadows covered now by the soft gray of seeding goldenrod, where migratory birds converse in the bushes while harvesting seed. Or you can choose the shady Hickory Lane to the west or the dappled light of the maple forest to the north if you’re in the mood for a woodland walk.   

Text & photos by Cam Mannino

My visits were scattered throughout the month –  unusually warm days early on, a sunset hike one breezy evening, and finally a cold, rainy morning right before first frost. Each time I rediscovered how sensibly nature prepares for a winter rest and a bountiful spring. 

 

 

Cranberry Lake Itself  – A Thwarted Kingfisher, a Remarkable Grebe, and Diving Ducks of All Kinds

The edge of Cranberry lake at the end of an eastern trail.

Cranberry Lake welcomes all kinds of water birds as they begin their long journeys to southern climes. One cold, wet morning, I watched a bird hovering vertically high above the water, head down, scanning the surface below. Suddenly, it gave a loud rattling cry and headed for a leafless tree near the shore. An agitated male Belted Kingfisher (Megaceryle alcyon) shouted its noisy call from a bare limb. Perhaps he was put out by not spotting prey from that perch either!

This male Belted Kingfisher had one slate blue belt on his chest. The female has a chestnut brown belt and a blue one.

A small Killdeer (Charadrius vociferus) flew in to probe the edge of a mud flat, landing near a Canada Goose (Branta canadensis). Quite an odd couple!

A Killdeer shares a mud flat in the lake with a Canada Goose.

Killdeer are wading birds, being Plovers, but I’ve most often seen them in barren fields, either scurrying along scaring up insects or keening in flight to distract predators.  This one, though, looked right at home as it probed the mud for insect larvae or other aquatic prey before beginning migration.

Far out on the lake, a huge mixed flock of migrating ducks and other water birds, well over 200 of them, floated on the surface, foraged for food, or slept and preened on the mud flats in the shallower parts of the lake.

Part of a huge flock of diving ducks on Cranberry Lake

After studying the photo magnified, Ben guessed that most of the birds were Ring-necked Ducks (Aythya collaris) which are diving ducks. Unlike mallards and other dabbling ducks who simply tip upside down to feed, diving ducks have legs set far back on their bodies.  As a result, they need to run across water, wings flapping,  to get into the air and are awkward on land – but they dive, feed and swim underwater with ease!

(Since most of the Cranberry Lake flock was far from shore, the closeup photos of diving ducks below are all from inaturalist.org photographers. My thanks to all of them and to Creative Commons where they license their work.)

Two other diving ducks that Ben thinks may have been in this flock include Redhead (Aythya americana) which are so social that they’re also referred to as “rafting ducks” and  Lesser Scaup (Aythya affinis). According to the Cornell Ornithology Lab, Lesser Scaup chicks “are capable of diving under water on their hatching day, but they are too buoyant to stay under for more than just a moment. By the time they are 5 to 7 weeks old they are able to…swim underwater for 15-18 meters (50-60 ft).” Here’s a wonderful closeup of a Redhead by photographer lonnyholmes and a Lesser Scaup photo by photographer Paul Sullivan. (Hover cursor for captions; click on photos to enlarge.)

Far out in the lake, through my binoculars, I also spotted Bufflehead, another diving duck,  on their way from the boreal forests of Canada and Alaska, where according to Cornell, they “nest almost exclusively in holes excavated by Northern Flickers and, on occasion, by Pileated Woodpeckers.” Unfortunately the male and three female/juvenile Bufflehead that I saw at were too far for my longest lens to reach clearly. So on the left is my distance photo from Cranberry Lake (click to enlarge) and  on the right is a closeup from a  photographer at inaturalist.org who uses the name dlbowls showing the male’s dark head iridescent in the sunlight.

Feeding alone on a rainy morning, the solitary  Pied-billed Grebe (Podilymbus podiceps) dove repeatedly into the gray surface of the lake. Modest brown this time of year,  these grebes bills turn white with a neat black band in breeding season. Pied-billed Grebes control their buoyancy by trapping water in their feathers. According to Cornell Lab, this allows them to escape danger by doing what children might call “belly smackers” – “plunging with head and tail raised above the belly, making a splash. They can also dive head first, or simply sink quietly out of view, leaving no trace. Parents dive with young clamped under their wings … These grebes often avoid danger by submerging, crocodile-style, with just the eyes and nostrils above the surface.”

The little grebe at Cranberry Lake gave me a brief demonstration of the submerging tactic –  first trapping water in its feathers , then settling back down on the water, and finally beginning to submerge like a little submarine.  What a trick!  I’m very taken with this little bird.

Wide, Sunny Meadows Surrounded by Autumn Color

A meadow on the north end of the park

On the trails that lead toward the meadows, small brown birds dash from bush to bush or dart down into the grass.  Some are tiny migrators who might appear modest and plain until you see them through binoculars or a camera lens. Chubby White-throated Sparrows (Zonotrichia albicollis), with their yellow “lores” and striped heads, hung out in small flocks, keeping in contact with soft seep calls.

The White-Crowned Sparrow has yellow “lores” – spots in the corners of its eyes.

Another brown migrant paused in the bushes along the trail from the lake – the Hermit Thrush (Catharus guttatus). These normally solitary birds are often quite secretive – hence the name, perhaps? They’re well-dressed hermits, though, with their chocolate back, spotted breast and white eye ring. And during migration, they do sometimes forage with or near other small birds.

The Song Sparrow (Melospiza melodia) is silent now, no longer burbling its song from high in a bush as it did this spring and summer. In fact, this one glowered from the bare branches, seeming a bit put-out by my presence. Or maybe it’s just irritable about having to migrate, though  it will only travel a short distance to the south.

At the edge of a small meadow, a year-round resident, the American Goldfinch (Spinus tristis) pecked delicately at the seeds of Common Evening-Primrose (Oenothera biennis) that nicely complemented its muted gold.

And another year ’rounder, the Northern Cardinal (Cardinalis cardinalis) stared from the drooping vines of Oriental Bittersweet (Celastrus orbiculatus), an aggressive, invasive plant that strangles, shades out and topples trees. Two trees along the trail had fallen recently due to masses of this vine in their canopies. Those orange and red fall fruits are disastrously appealing to birds, who spread their seeds far and wide.

On my early October visits, insects were still very much in evidence. One warm October afternoon, a busy group of adult and juvenile Large Milkweed Bugs (Oncopeltus fasciatus) fed eagerly on the seeds of Common Milkweed (Ascelpias syriaca) in a southern meadow. The large beetles below are adults accompanied by the mostly red juveniles. They eat milkweed seeds by injecting saliva through the seed’s surface which liquifies it so it can be sucked through their straw-like rostrums. Milkweeds produce lots of seeds, so luckily these beetles, though destructive to individual pods, don’t really do a lot of damage in a season. And they are kind of jazzy looking, don’t you think?

Red-legged Grasshoppers (Melanoplus femurrubrum) mate in the autumn and lay their eggs in the earth. The eggs won’t finish developing until spring, when the first nymphs emerge. They’ll molt 5-7 times during the summer before they are fully adult, like this pair on a grassy trail.

A female (left and larger) and male Red-legged Grasshopper will lay eggs that will hatch next spring.

As October moved on, the goldenrods – Canada Goldenrod (Solidago canadensis) and late blooming Showy Goldenrod (Solidago speciosa) – began to seed, casting a silver-brown patina over the meadows.

Despite the cooler days, the small Autumn Meadowhawk (Sympetrum vicinum) still glided along the meadow paths, stopping on a fallen Canada Goldenrod stem to warm its wings in the autumn sunlight. The yellow-orange blush on the wings near the thorax is a distinguishing field mark. Autumn Meadowhawks fly later than most other species in our area, but are usually gone by early November, having laid their eggs along the lake’s shoreline.

The Hickory Lane and Wooded Wetlands – Filtered Light, Foraging Nut Eaters, a Frog and Puffballs

The Hickory Lane at sunset

Woodland walks are magical in the early morning or just before sunset. The light filters down through a golden shimmer of falling leaves and sometimes sets a crimson leaf aglow.

A Silver Maple leaf (Acer saccharinum) in the northern forest  set aglow in morning light.

On a warm walk in early October, the bright yellow caterpillar of a Spotted Tussock Moth (Lophocampa maculata) caught my eye within the dry leaves on the Hickory Lane. Such a fancy caterpillar! Research in Caterpillars of Eastern North America seems to indicate that  it’s the middle instar of the Spotted Tussock moth because in earlier stages, the end sections of this yellow caterpillar are completely black – but I’m open to correction by more knowledgeable readers!

An Eastern Chipmunk (Tamias striatus) on the Hickory Lane basked in the sunset, perhaps resting from a long day of ferrying nuts in its cheeks to stock its underground burrow. It won’t hibernate, but when it wakes periodically from its winter torpor, it will need a little sustenance before snoozing again.

An Eastern Chipmunk rests from its seed and nut-gathering labors before winter.

A Gray Squirrel (Sciurus carolinensis) dashed quickly up a tree on the Hickory Lane (in this case, it’s the black morph). And nearby, an American Red Squirrel (Tamiasciurus hudsonicus) did the same. I wondered if they had enjoyed some of the hickory nuts that were neatly opened on a fallen log not too far away.

Almost invariably, curious deer emerge at the edge of the woods, and they too are putting on weight for winter. They eat lots of nuts, including plenty of acorns, this time of year. Their love of acorns in the fall and saplings during the winter can make it harder for our oak forests to regenerate. This doe looks like she’s definitely eaten her share and is ready for cold days ahead!

In a pond hidden in the trees, a Muskrat (Ondatra zibethicus) had built a roomy “push-up” den in which it can eat above the water line. Muskrats don’t hibernate, but spend the winter cruising very slowly beneath the ice. What appears to be a hole is probably just plant matter or mud, since muskrats generally enter their push-up dens from under the water through a tunnel that leads up to a cavity at the center.  According to Wikipedia, “In snowy areas, they keep the openings to their push-ups closed by plugging them with vegetation, which they replace every day.”

Near that woodland pond in late October, a tiny masked Wood Frog (Rana sylvatica) literally sat “like a bump on a log,” staring off into the distance, partially lit by the green light of a leaf. Wood Frogs love forested wetlands like this during the summer. But this little frog may be preparing for winter. It will move upland, away from the water, burrow under leaves or a log. Then most of the water in its body will freeze solid, and its breathing and heartbeats will stop! But it will thaw in the spring and go right back to the pond to mate. Hope this little one finds a cozy spot before long.

The astonishing Wood Frog freezes solid in the winter and thaws out in the spring.

On a fallen long nearby, my husband and I came across  a colony of Puffball Mushrooms (division Basidiomycota) just as we did last year. These stalkless mushrooms would disperse spores on their own, of course, but I asked my husband to poke a couple in order to catch the brownish cloud of spores escaping through their tiny apertures. Wikipedia says falling raindrops disperse puffball spores in a similar way.

On my last visit just before first frost, under moist trees in these wooded wetlands, the Sensitive Ferns’ green, leafy, sterile fronds (Onoclea sensibilis) were already withering in the dropping temperatures. But the separate fertile fronds, covered in brown beads called “sori” that contain next year’s spores, stood erect in the grass beneath the trees.

Quietly Prepping for Winter and Another Spring

Cranberry Lake Park, like all of nature, provides testimony every autumn that the year is not “dying” as is so often said of this season. On the contrary. At every turn in the trails, nature is sensibly preparing for winter and sowing for spring. Yes, plants wither – but their seeds, stems, and roots wait within the soil for warm spring light. Gray-brown bracken will eventually fall, nourishing the soil in which those seeds can grow. Bright leaves fade and fall, of course, but only because trees are in “dormancy,” resting, slowing their metabolism, preserving themselves for next spring’s surge of growth. Some insects migrate, others winter-over under bark or within plants, while still others perish, leaving behind eggs which bide their time beneath the earth. Birds fly south, frogs burrow under logs, and animals of all sorts settle into winter quarters. Nature doesn’t resist change. It simply adapts to it, with every intention of burgeoning forth with gusto in the spring. We humans probably do best when we follow nature’s lead by just letting nature take its course –  preparing for longer nights and colder days, while confidently sowing seeds – both literally and metaphorically – for a future spring.

Bear Creek Nature Park: Young Birds, a Tiny Forager in Disguise and So Many Wildflowers!

Boneset and Joe Pye in the Eastern Meadow at Bear Creek

Late summer wildflowers nodded and swayed in the meadows, woods, wetlands and native gardens at Bear Creek this August. Monarch butterflies paused on the blossoms, competing mostly with industrious native bumblebees. And all over the park, young birds were feeding on their own – or in a few cases, still getting fed by doting adults. In the center pond, a tiny creature foraged in disguise!

So take a wander along the trails, as goldenrod transforms the park from green to gold, and enjoy the bright beauty of summer’s last hurrah!

 

Like Some Human Youngsters, A Few Avian “Adolescents” Stick Close to Mom or Dad

A young Eastern Kingbird (Tyrannus tyrannus) hid in a shrub in the eastern meadow, insisting loudly about being fed.  No parental response was forthcoming from the adult on a shrub some distance away. So eventually, the youngster ventured out into the field, looking about with curiosity. Seemingly satisfied with this move toward independence, the adult flew in to feed the youngster. And then they shared the bush a while until the adult flew farther off again. (Click on slideshow’s pause button for captions.)

Two groups of Mallards (Anas platyrhynchos) were escorting their young around the Center Pond. In one group, two males and a female floated along with a small juvenile. The males are now in their late summer “eclipse plumage” which makes them look very much like the females – except that the males have yellow bills, while females’ bills are orange and black. The males will change back to their glamorous, iridescent green head feathers later in the fall when Mallards choose their mates for next spring. I guess these two males on the right were sticking close to this female just in case she made an early decision!

A male Northern Cardinal (Cardinalis cardinalis) seemed remarkably calm at my approach as he concentrated on gathering seeds in his beak. Usually they dash off at the first sight of me when they’re on the ground. He wasn’t crushing the seeds, so I assume he had a nest nearby since cardinals can have up to four broods in a season. That’s a lot of parenting in just a few months.

A male American Goldfinch (Spinus tristis) plucked buds from native Canada Goldenrod  (Solidago canadensis) which is just beginning to bloom. He may have been feeding his young as well, since this is the nesting season for goldfinches.

While Adults Molt, Young Birds Forage on Their Own

Many bird species molt from mid-August until mid-September, including Field Sparrows, Downy Woodpeckers, House Wrens and many others.  The Eastern Kingbird, featured feeding its young above, doesn’t molt until it reaches its winter territory in South America. It’s occurred to me that since birds go into hiding during the molt, perhaps their young have to be a bit more independent sooner than other birds. Just a guess. In any case, a lot of young birds are out and about, clumsily trying to forage on their own.

I saw what I think is an adult Song Sparrow (Melospiza melodia) just beginning its molt. The bird’s feathers looked oddly fluffed out and it was picking at its breast in a persistent way. It might be a male since they molt a bit earlier than females. Below, a group of young song sparrows hopped along the trail, seeing what they could find in the grass before flying up into small trees nearby.  (Click on photos to enlarge; hover cursor for captions.)

Downy Woodpecker adults (Picoides pubescens) are molting now too. The Stokes Guide to Bird Behavior (Vol II) says “[Downy] Fledglings in general can be told from adults by the clearly new, white feathers on their breast. Adult have gone in and out of the nest hole hundreds of times by this stage and look very worn, with bits of black showing through their white breast feathers.” The feathers on the young female I saw looked wonderfully fresh as it tried to drill into a branch, so I’m guessing it’s a foraging juvenile.

Down at the Center Pond, a Green Heron rested calmly on a log. Since spring, I’ve repeatedly seen a Green Heron in that very place, so I’m thinking it’s a mature bird. Cornell contends that Green Herons are sometimes found in colonies. But I’ve never seen more than one of these solitary birds at a time.

The same heron flew up onto a bare limb, staring into the water.

Two other solitary birds could have been adults or juveniles. It’s hard to distinguish with the House Wren and the Black-capped Chickadee once they’re out on their own. The House Wren may have been a youngster since it was clearly curious, but the Chickadee appeared to be a sophisticated contortionist as it probed a stick for insects.

Glorious Wildflower Color, Exuberant Vines and a Few Pretty-but-Toxic fruits in the Woods and Shady Wetlands

Though wildflowers are not generally as numerous on the shady paths of Bear Creek, you don’t want to miss them. So keep an eye out for their exotic shapes and vivid colors shining out of the greenery as you make your way, especially near wetlands. I just learned from Wikipedia that the Jack-o’lantern mushrooms (Omphalotus olearius) below are even bio-luminescent and their gills glow faintly green in the dark when they’re fresh! Hence the name, eh?

Native Wildflowers and Grasses Bask in the Sunlight of the Meadows and Native Gardens

A spray of Purple Coneflowers in one of the native gardens

In the native gardens, the center of the parking lot, and scattered across the sunny meadows, native wildflowers bloom among the Canada Goldenrod and the Queen Anne’s lace. The monarchs seem to be enjoying them. A female sipped nectar from the Purple Coneflower and a male spread his beautiful wings on the Joe-Pye. (The field marks for males are bulges in the veins on their hind wings.) Here’s a sampling:

A Quarter-sized Creature Dons a Bubble Disguise

One cloudy afternoon, my husband spotted a very small clump of bubbles, green Water Meal  (Wolffia coumbiana) and Duckweed (Lemna minor) moving slowly around the water of the center pond near the dock.

A moving patch of Water Meal, Duckweed and bubbles on the Center Pond caught our eye.

At first only the yellow/green striped head of a tiny Painted Turtle (Chrysemys picta) peeked out of the bubbly mass.

The tiny head of a Painted Turtle emerged from the bubbly greenery floating in the pond.

At last, we could see this tiny creature – a turtle about the size of a quarter – who’d found a nifty disguise to wear while munching on the Water Meal and Duckweed greenery that covers the pond. I’m betting on this little one to survive to adulthood!

A Painted Turtle – about the size of quarter! – brings its head and shell into the sunlight.

Perhaps when this baby gets a little bigger, it can join the Painted Turtles who hang out on this log at the east end of the pond almost every warm day. Last Saturday, this group seemed to be doing a slow motion version of the Hokey-Pokey (“You put your left leg in, you put your left leg out”), except for that one member who is not quite with the program!

 The Delight is the Details

Western slope of Bear Creek in mid-August

Meadows like the one shown above on the western slope are an eye-full on a summer day. The sweeps of green, yellow and white against a blue sky soothe the spirit like a cool hand on a fevered brow.  Soak it in.  You can feel yourself unwinding.  Then look a little closer.  So much of the delight in nature comes from noticing small things – like the turtle in its bubble disguise, the scarlet cardinal flower shining in a shady wetland, or a parent bird feeding its young on a leafy branch. Like any great work of art, there’s always more to see in nature’s landscapes than what comes quickly to the eye. So perhaps spend a few quiet minutes looking down into the water or into the tall grass. Scan the treetops through your binoculars. The smallest discovery can add just a little more joy to a walk in the park.
